Authority sanction alone predicts contact–prejudice reduction as strongly as multiple optimal conditions do.

Evidence

Given that none of the three conditions emerged as a significant, independent predictor, additional analyses were conducted to examine whether authority sanction might play a special role in predicting the contact–prejudice effect sizes. For this analysis, samples rated as having only authority sanction (k 31) were compared with samples rated as having two or more of Allport’s conditions (k 103) as well as with the remaining samples in our analysis (k 564). Results show that the mean effect for samples with only authority sanction (mean r .286) did not differ significantly from the mean effect for samples with two or more of Allport’s conditions (mean r .290), QB(1) 0.01, p .93, whereas both of these groups showed significantly stronger effects than did the remaining samples in our analysis (mean r .204), QB(1) 6.10, p .05, and QB(1) 16.18, p .001. — Thomas F.
